Assay

Tap a word in any reply — it highlights, with a small bar: ＋ Add collects it, ✎ Note annotates it now (choose whether the note sits before or after the quote), and a verb row — Keep Push Tweak Reword Challenge Cut — collects it classified in one tap; the verb becomes a plain-English clause in the prompt. Tap the highlight to widen it — word → sentence → paragraph → back to the word. Tap other words in the same reply to grow the selection toward them, word by word — into the next paragraph too. A tap further off is a different passage, so it starts a new selection there rather than dragging the highlight across everything between. This works inside the cards ChatGPT renders in the chat too — a canvas draft, or a message swapped into an edit box — and on a phone the caret is handed back, so the keyboard stays down. On GitHub and Gist it runs over a file instead of a reply, and a multi-file gist exports one section per file. To start over: ✕ on the bar, or tap a different reply or empty space. Long-press selection still works for arbitrary spans.

Each fragment gets the next of six rotating highlight colors, and collected marks stay tinted on the page while you keep reading — they are found again after a page refresh, so a reload costs you nothing. Tap the Assay pill to flip between the fragment view and the conversation — the page stays scrollable behind it and taps keep collecting. ChatGPT drops documents into a reply as editable cards; Assay reads them back as ordinary conversation text so a tap selects in them like anywhere else — ⚙ in the tray holds the settings, including Cards: editable, which hands them back to the site's editor. Tap a passage you already collected and the same bar opens on it — change its verb, rewrite its note, or Remove it. In the list: the same, plus flip a note between before/after, delete strays, expand truncated text with a tap. Each conversation keeps its own list (fragments collected in a brand-new chat follow it once it gets its address); a shared cross-conversation list may come later.

↗ To composer writes just your fragments and annotations into the composer — no added prompt text; your annotations carry the intent. Review, then send. If injection is ever blocked, it lands on your clipboard instead.

⬇ .md / ⬇ .txt download the conversation to your phone — named assay-<chat title>-<timestamp> — with your collected fragments and notes appended — nothing is sent or cleared. A picker opens first, listing every message with its author and a preview so you can take the whole thread or just part of it: ↓ on a message takes it and everything after. Both sites load older messages only as you reach them, so an export holds what the page was showing when you pressed the button — or press ⤓ Walk the whole thread in the picker — the quiet amber one, which asks first — and it walks the thread for you: to the top, unfolding anything behind a “show more”, reading each screenful on the way back down, then putting the page back where you were. It blocks while it runs and has a Stop; what you had already ticked survives it. The picker shows every message it found with its length; tap a size to read it. Nothing of Assay is attached to the page between exports, so scrolling, typing and a reply streaming in cost it nothing at all.

Clear and sent batches are restorable from the empty sheet, so nothing is lost by accident.
